The cuticle near the caudal end is slightly expanded and dorso-ventrally flattened at the sides. The cloaca opens into a deep longitudinal depression in the cuticle (fig. 4^ c). The spicules are unequal in length, but both very short. The right spicule measures 0*35 mm. and is straight ; the left measures 0*4 mm. and is Fio-. Anisakis physeteris. Caudal end of male; ventral view. c, edge of cloacal depression; L, left, and r., right spicule. slightly curved. The caudal papillae (fig. 4) are irregularly arranged, and there is no clear distinction between the post- anal and preanal series. Near the extremity of the tail there are four pairs arranged in a fairly regular series. In front of these, and separated from the most anterior of them by a considerable space, there is a pair of double papilla situated on the folds of cuticle forming the lateral walls of the cloacal depression. Anteriorly to these, at the level of the widest part of the cloacal depression, is a pair of simple Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London, Taylor and Francis, Ltd
